  Change Pico to ESP32 with OpenWeatherMap to display weather!

  Code:

  import urequests
  from irm import IRM
  from machine import Pin
  from weather_sprites import WEATHER_SPRITES
  import time
  import json
  
  data = {    "api_key": "YOUR_API_KEY_HERE",    "city_name": "YOUR_CITY",    "units": "metric",
  }
  weather_url = "https://api.openweathermap.org/data/2.5/weather?q={city_name}&appid={api_key}&units={units}"
  
  
  irm = IRM(Pin(13), [[1, 2],                    [4, 3]])
  irm.brightness = 50
  
  res = urequests.get(url=weather_url.format(**data))
  data = json.loads(res.text)
  print(data)
  weather_icon = data["weather"][0]["icon"]
  temp = data["main"]["temp"]
  irm.clear()
  irm.draw_sprite(0, 0, WEATHER_SPRITES[weather_icon])
  irm.draw_text(0, 0, temp, irm.FONT5, [0, 255, 100])
  irm.write()

  To draw all the icons from OpenWeatherMap, I also made a simple editor Matrix Helper from scratch. To help me generating sprites. It grabs the import image, resize it, and generate it into matrix style, then you can edit detail pixel and convert it into code. More about Matrix Helper will be soon on another project.
